What are some practical use cases for events in Vue.js?

In Vue.js, events are crucial for handling user interactions. Common use cases include form submissions, button clicks, and custom events for component communication.

Can you give me an example of handling a button click event?

Sure! You can use the @click directive in your template. For example: <button @click="handleClick">Click Me</button>, and in your methods, define handleClick() { console.log('Button clicked!'); }.

What about using events for form validation?

You can listen for the submit event on a form. For instance: <form @submit.prevent="validateForm">, where validateForm checks the input values before submission.

How can I create custom events between components?

You can use the $emit method to create custom events. For example, in a child component, you can call this.$emit('myEvent', data) to send data to the parent.
